What is the difference between these two commands?

I tried $ which l

, but there is no way out.

There is also no result for $ man l

.

I also tried unsuccessfully to use it on Google.

l

is probably an alias for something like ls -F

. The option -F

forces ls

you /

to add to directory names, *

to executable regular files, etc.

UPDATE: As per your comment l

has an alias ls -CF

. Single letter variants can be "included", therefore ls -CF

equivalent ls -C -F

. This option -C

forces the ls

display of records by columns. This is the default if it ls

thinks it is writing to the terminal; the option -C

does it this way unconditionally. ( ls -1

lists one entry per line, which is the default if ls

is * is not written to the terminal.)



type -a l

should show you how it is defined. It is probably set to $HOME/.bashrc

.

( $

is part of your shell prompt, not part of a command.)

As far as I know, there is no generic 'l' command that exists or even does what 'ls' does, why your results are for which l

and man l

are empty



Do you have something in your path called l

that possibly launches ls

?

To see if its alias is checking the ~ / .bashrc file

$sudo cat ~/.bashrc | grep 'alias l='
alias l='ls -CF'

the specific bash command for "ls".
